I can vouch that some plastic inner sleeves leach some sort of nasty residue onto LPs. For instance,
a while back I bought a load of original-pressing Pablo records from the late 70's thru mid 80's,
still wrapped in plastic. Most had paper inner sleeves but the Pablo Digital issues had
plastic-lined inner sleeves. In a few cases, not all cases though, the plastic inner sleeve was
firmly attached to the record. I could carefully peel it off but there was a residue that did not
come off with VPI treatment, including with a liquid containing isopropynol. The net result was
noisy surfaces, not groove distortion but really noisy surfaces. I can't understand why some of
those records had this problem but not others. All were from the same defunct record shop and all
had been warehoused under similar conditions.
Plastics -- unstable chemistry by definition.
As a result of this experience, I avoid replacing inner sleeves with plastic. I handle my records
carefully and store them carefully and have not had any issues using smooth paper inner sleeves.
